摘要

随着移动通信新技术的发展，移动数据传送对时间误差要求越来越高，高精度的网络IP时钟不但能够提升网络吞吐量，同时也能提高网络传输带宽。通过分析网络IP时钟同步时误差的产生机制，提出一种自动对称补偿算法消除时钟同步中产生的误差，并对这种误差算法进行实际验证。测试结果表明，自动对称补偿算法，将大幅度降低IP时钟同步时的误差值，有效地提升了IP时钟的同步能力。%With the development of mobile communication technology, the accurate demand on time-error is higher and higher in mobile data transmission. High-precision network IP clock not only enhances network throughput, but also im-proves network bandwidth. Through analyzing the error generation mechanism of the network IP clock synchronization, an automatic symmetrical compensation algorithm to eliminate errors caused by clock synchronization is proposed, and this error algorithm is verified in practical application. Test results show that the automatic symmetrical compensation algorithm will drastically reduce the IP clock synchronization error value, effectively enhances the IP clock synchronization capability.
